MK-4 Heavy Duty Extend

**All masts are kits and include fiberglass tubes and corresponding quik-clamps**

The MK-4 Series of masts are, by far, our most portable masts for many reasons. The masts are light weight and short enough, when fully collapsed, to manipulate the quik-clamps from the ground. This mast will get you above most obstacles to achieve maximum height, line-of-sight, maximum gain, and the best reception. Our masts are completely adjustable along the entire length of each tube. The MK-4 Series of masts are perfect for most portable applications.

See the photo gallery to see dozens of pictures, all taken by customers, of our mast systems being used for a number of different applications.
